By now you’ve learned the very distinct distinction between diamond ‘cuts’ and diamond ‘shapes’ (you’ve been religiously reading this blog, right?).  So now we are ready to dig a little deeper into the different diamond shape varieties and their diverse and dynamic origins.  There are 10 major shape classifications, each one shapelier than the next.
